A basic display tells you what the room is doing while you are awake to look at it. This logs, so you can see what happened at 3am and whether the change you made last week actually did anything. That is a different tool from a thermometer, not an expensive version of one.

The Deep Dive
The reading you never take
People measure their bedroom at bedtime — the moment the door has been open, the room is at its coolest and nobody has been breathing in it for six hours. By 3am, with the door shut and one or two people asleep, it can be several degrees warmer and considerably more humid. That is the number that fragments the second half of the night, and a display cannot show it to you.
Use it for a fortnight, then stop
This is a diagnostic instrument rather than a permanent fixture. Run the experiment — step the thermostat down a degree every three nights, or test whether cracking a window helps — read the charts, make the change, and then the device has done its job. Leaving it on the wall forever is fine but it is not where the value was.
When the cheap one is the right answer
If you just want to know whether your bedroom is in the right range, a basic display costs a fifth as much and tells you. Logging is worth paying for when you have a question that requires a before and after.

Key Features
Logs history
The 4am reading, kept
Charts the overnight curve instead of showing a single moment, which is where the useful information lives.
Remote reading
Check without going in
Useful for a nursery or a spare room, and for checking a bedroom that has been closed all day.
Humidity too
The other half of comfort
Dryness causes the morning sore throat people blame on illness. Logged alongside temperature, the pattern is obvious.
Supports an experiment
Change one thing, measure it
The point of tracking is to test a change. A week of before and after settles it.
Frequently asked questions
Why do I need logging rather than a display?
Because the reading that affects your sleep happens while you are asleep. A display answers "is the room right now"; a log answers "what did the room do overnight, and did last week's change help".
What am I looking for in the data?
Temperature between 60°F and 67°F and humidity between 40% and 60%, held through the night rather than at bedtime. The overnight rise with the door closed is what usually surprises people.
Is it worth four times the price of a basic unit?
Only if you will look at the data. If you want to know whether your room is broadly in range, buy the cheap display. If you are running a change over a fortnight, this answers the question and the cheap one cannot.
